Stainless Steel 316 Dowel Pins
Marine-grade austenitic stainless — superior corrosion resistance.
316 is the default when the part will see saline, cleaning chemistry, or repeated autoclave cycles. The molybdenum addition over 304 buys meaningful pitting resistance, which is why it dominates medical and marine work. It is gummier to machine than the free-machining grades and work-hardens readily, so it is turned slower here — that shows up in the price rather than in the finished tolerance.
Most 316 pin work that comes through here is medical: instrument frames, handpiece internals, and fixturing that has to survive the same wash cycle as the parts it holds. If the assembly sees saline or repeated autoclaving, 316 is the safe answer, and it and 303 sit close enough together that the decision is about the environment rather than the quote.
Any size, not a series
There is no size list here because there is no catalogue: diameters run from 0.015" to 0.375", including sizes between two standard ones, and lengths from 0.02" to 4" — turned to order rather than cut down from a stock pin and re-finished. Pricing in Stainless Steel 316 starts at $2.86 per piece at 100 off, and falls further at higher volumes.
